Abstract

A lock nut system includes a nut, a keeper engagement with the nut to inhibit movement of the keeper relative to the nut, and a keeper retaining member. The keeper has a radially inner side configured to engage a shaft to inhibit rotational movement of the nut relative to the shaft when the keeper engages the nut and a radially inner side engages the shaft. The keeper retaining member is secured to the keeper and is engageable with the nut to hold a keeper axially such that keeper is engaged with the nut. A cover member is located on an opposite side of the keeper retaining member relative to the nut and engaged to the keeper retaining member to inhibit a separation of the cover member from the keeper retaining member in such that that the separation of the cover member from the keeper retaining member provides a visual indication to a user.

First claim

The invention claimed is:

1. A lock nut system comprising:
a nut;
a keeper engageable with said nut to inhibit movement of said keeper relative to said nut;
said keeper configured to engage a shaft to inhibit rotational movement of said nut relative to the shaft when said keeper engages said nut and said keeper engages the shaft;
a keeper retaining member secured to said keeper, said retaining member engageable with said nut to hold said keeper engaged with said nut; and
a tamper indicating member contacting said keeper retaining member such that a separation of said tamper indicating member from said keeper retaining member deforms said tamper indicating member to provide an indication of tampering to a user.

2. The system of claim 1 wherein said retaining member comprises a notch and said tamper indicating member comprises a tab located at a position relative to said notch of said retaining member such that said tab is deformable into said notch to connect said tab to said retaining member.

3. The system of claim 1 wherein said tamper indicating member comprises an indentation and an external circumference, said indentation providing an opening on said external circumference to allow a portion of said retaining member to be viewed from a side of said tamper indicating member opposite said nut.

4. The system of claim 3 wherein said retaining member comprises an engaging portion engaging said nut, said indentation is located relative to said retaining member to allow the user to view the engaging portion through said opening.

5. A lock nut system comprising:
a nut;
a keeper engageable with said nut to inhibit movement of said keeper relative to said nut;
said keeper configured to engage a shaft to inhibit rotational movement of said nut relative to the shaft when said keeper engages said nut and said keeper engages the shaft;
a keeper retaining member secured to said keeper, said retaining member engageable with said nut to hold said keeper engaged with said nut; and
a tamper indicating member connected to opposite portions of said retaining member such that a separation of said connecting member from said keeper retaining member provides an indication of tampering to a user.

6. The system of claim 5 wherein said retaining member comprises a notch and said tamper indicating member comprises a tab located at a position relative to said notch of said retaining member such that said tab is deformable into said notch to connect said tab to said retaining member.

7. The system of claim 6 wherein said tamper indicating member comprises an indentation and an external circumference, said indentation providing an opening on said external circumference to allow a portion of said retaining member to be viewed from a side of said tamper indicating member opposite said nut.

8. The system of claim 7 wherein said retaining member comprises an engaging portion engaging said nut, said indentation is located relative to said retaining member to allow the user to view the engaging portion through said opening.

9. A method for use in providing a load on a bearing mounted to a shaft, the method comprising:
engaging a keeper with a nut mounted on a shaft to inhibit movement of the keeper relative to the nut;
engaging a retaining member connected to the keeper with the nut to hold the keeper engaged with the nut;
aligning a first pressing member of a plurality of pressing members of a tool with a first tab of a plurality of tabs of a tamper indicating member and pressing the first member against the tab to engage the tamper indicating member to the keeper retaining member such that a separation of the tamper indicating member from the retaining member provides a visual indication to a user.

10. The method of claim 9 wherein the retaining member comprises a notch and the tamper indicating member comprises a tab, and the pressing further comprises deforming the tab into the notch to connect the tamper indicating member to the retaining member.

11. The method of claim of claim 10 wherein the deforming the tab comprises rotating the tab toward the retaining member about a point connecting the tab to a remainder of the tamper indicating member.

12. The method of claim 9 further comprising viewing a portion of the retaining member from a side of the tamper indicating member opposite the nut through an opening bounded by an indentation in an external circumference of the tamper indicating member.

13. The method of claim 12 wherein the retaining member comprises an engaging portion engaging the nut, and wherein the viewing the portion of the retaining member comprises viewing the engaging portion engaging the nut.

14. The method of claim of claim 13 wherein the tab comprises a first tab of a plurality of tabs of the tamper indicating member, the deforming comprises the plurality of pressing member contacting a plurality of tabs of the tamper indicating member to deform the plurality of tabs toward the retaining member.

15. An apparatus for use in connecting a tamper indicating member to a retaining member coupled to a nut mounted to a shaft, the apparatus comprising:
a plurality of pressing members extending axially from a main body portion;
a contacting portion coupled to said main body portion and having a plurality of openings aligned with said pressing members to allow a first pressing member of said pressing members to extend through said contacting portion to contact a tab of a tamper indicating member to deform said tab toward a retaining member coupled to a nut mounted on a shaft.

16. The apparatus of claim 15 further comprising a resilient member between said main body portion and said contacting portion to bias said main body portion and said contacting portion away from each other and to bias said pressing member to a retracted position away from said tamper indicating member when a force is not applied to said main body portion toward said tamper indicating member.

17. The apparatus of claim 15 further comprising a first aligning post and a second aligning post connected to said main contacting portion and extending away from said main body portion, said first aligning post and second aligning post spaced from each other such that said first aligning post and second aligning post are receivable in a plurality of spacing openings in the tamper indicating member to align said first pressing member with said tab to allow said first pressing member to deform said tab.
